Embodiment 1

[0010] Embodiment 1: refer to figure 1 , figure 2 , image 3 , In this embodiment, a groove parallel to the length direction of the skeleton is provided on the skeleton of the light steel keel. Because of the specific structure of the groove, the impact resistance and compressive strength of the present invention can be improved.

Embodiment 2

[0011] Embodiment 2: refer to figure 1 , figure 2 , image 3 In this embodiment, on the basis of Embodiment 1, the cross-section of the groove is designed as a trapezoid, and two chamfers are respectively made at the two corners of the lower bottom of the trapezoid, and the chamfers are located at the notch of the groove. A rubber strip is provided, and the recess of the groove is provided with a restrained closing (chamfer) so that the rubber strip does not fall off from the trapezoidal groove, and at the same time increases the contact area between the rubber strip and the keel, so as to improve the sound insulation effect and Impact and compressive strength.

Embodiment 3

[0012] Embodiment 3: refer to figure 1 , figure 2 , image 3 , Figure 4 In this embodiment, a light steel keel frame with rubber strips inlaid in the trapezoidal groove at the inward constriction is selected, and at least two light steel keel frames are pasted with decorative panels as non-load-bearing walls in the building, so that the building wall has Better sound insulation effect and impact resistance, compressive strength, but also improve the overall firmness and stability of the building wall.

Abstract

The invention relates to a building material, in particular to a light steel keel and a construction wall body made of the same. The light steel keel comprises a skeleton, wherein a groove parallel to the length direction of the skeleton is formed in the skeleton, and a rubber strip is embedded into the groove. The construction wall body adopts the structure that a decorative board is posted on the two skeletons; one groove parallel to the length direction of the skeleton is formed in the skeleton, and one rubber strip is embedded into the groove. By adopting the technical scheme, the structures of both a current skeleton and a construction wall body are changed, an excellent damping and weakening effect is played in a sound wave conduction process, and the transmitting energy of the sound wave is greatly consumed; particularly, when being used as a separation wall body, compared with a separation wall body made of a common keel, the construction wall body provided by the invention has better sound proofing performance, shock resistance and compression resistance. Tests show that compared with the prior art, the effect of sound insulation in different audio regions can be obvious improved, which can reach more than 5db.

Description

technical field [0001] The invention relates to a building material, in particular to a light steel keel for a non-load-bearing wall of a building and a building wall made of the light steel keel. Background technique [0002] The light steel keel of the prior art and the building walls made of the light steel keel generally have the problems of poor sound insulation effect and / or low impact resistance and compressive strength due to the structural reasons of the light steel keel skeleton, which has affected the public quality of living and construction quality of buildings. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a light steel keel with good sound insulation and shock absorption performance and a building wall made of the light steel keel, which overcomes the defects of the prior art. The technical solution adopted by the present invention to solve the technical problem is: a light steel keel, which inc...
